This week consisted mostly of work with the rest of the team relating to the proposal presentation as well as the parts list so we could begin ordering parts that we needed as soon as possible. For the parts list, I worked alongside DJ and David to select light sources and receivers. I also did research to find an appropriate microphone for us to use initially and in our final product. I settled on initially using a small I2S MEMS breakout board we can get from Adafruit that seems to be a good base for initial testing. We also found a similar form factor bone conduction microphone that could serve our purposes but does not come with nearly as much documentation or additional components as the breakout board does. Initially, the Adafruit breakout board should serve well and then we could transition to the bone conduction solution if we are confident on other aspects of the project. Since I am more focused on the hardware for this project, I am not able to make as much tangible progress on the project until parts arrive, but I have been doing research and thinking about how we want to integrate all of the parts of the project. As of now, I am also acting support for other parts of the project such as the design review slides and documentation.
Our progress is on schedule, but I am hopeful that the parts that we need to get started come in soon so that I can start with testing and assembly of circuitry. Since we were proactive with part selection and ordering, this should not be a problem.
Next week I will primarily be focused on helping the rest of the team with the design review slides and report. For deliverables, I want to develop a testing plan and framework so that we can hit the ground running once our parts arrive.
